UNITED STATES PATENT OFFICE.

THOMAS A. OLOUGH, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TOTHOMAS J. BIGGER, OF SAME PLACE.

MECHANICAL DYEING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 459,744, datedSeptember 22, 1891.

Application filed April 19, 1889.

To all whom it may concern:

Be it known that I, THoMAs A. OLOUGH, a citizen of theUnited States, anda resident of Philadelphia, Pennsylvania, have invented 5 certainImprovements'in Mechanical Dyeing Apparatus, of which the following is aspecification.

The object of my invention is to construct a machine for treating yarnin hank or skein for the purpose of dyeing, scouring, or bleaching thesame. This objectl attain in the following manner, referencebeing had tothe accompanying drawings, in which- Figure 1 is a sectional view of theimproved machine, and Fig. 2 is a plan view of the same.

A is a vat or tank containing the dyeing, scouring, bleaching, or otherliquid to be used, this tank being circular in form, and centrallysituated in the tank is an upright bearing-block B, through which ispassed a driving-shaft C. This shaft O is stepped in a bearing securedto the bottom of the tank, and on the shaft 0 is a bevel-wheel c,meshing with a bevel-pinion d on a shaft D, which has its bearings inbrackets O and C The shaft D is the driving-shaft of the machine, and isprovided in the present instance with fast and loose pulleys (1 61 Onthe upper portion of the shaft 0 is a clutch-rin g E, which restsdirectly upon the bearing B.

F is a yarn-carrying frame driven through the medium of the clutch E bythe shaft 0, said frame F having a clutch-face'F, the teeth of whichengage with the teeth of the clutch E, so that on driving the shaft 0the frame F will be revolved. The frame F has a central orifice, intowhich projects the end f of the shaft 0, which acts as a pivot for theframe.

On the top of the frame F is an eye f, to which canbe attached the hookof a pulleyblock by which the frame can be raised, so that the yarncarried by the frame will be clear of the tank and can be removed and aduplicate of the frame inserted in position in the tank. On the outerring G of the frame F is a series of bearing-blocks g, and on the innerdisk G of the frame is a series of bearing-blocks g. Adapted to thesebearings g is a series of radial shafts 12, carrying roll- 5 ers a, onwhich the yarn to be dyed or other Serial No. 307,652- (No model.)

wise treated is hung. At its outer end each shaft 1) is squared andadapted to an opening in a drive-shaft M, adapted to the bearing g. Agear-wheel h on the shaft M meshes with an annular rack II on the edgeof the tank A, so that as the frame F revolves the shaft M and hence theshafts b will also revolve in their bearings The hanks of yarn w aresuspended on the rollers 0., carried by the shafts, and a loose rollera, hung in the loop of the hank of yarn, is of sufficient weight to keepa tension on the yarn at all times, so that the yarn when the machine isin motion not only travels through the liquid in the direction of thearrow in Fig. 2, around the shaft 0, but also has avertical movement inthe direction of the arrow, Fig. 1, and, if the level of liquid in thetank is as indicated by the lines in Fig. 1, two-thirds of the yarn willbe in the liquid at all times and change will be rapid, so that I amenabled by this machine to more quickly dye or otherwise treat the yarnthan heretofore and to produce more even shades in dyeing. The yarn isalways in sight of the attendant, who has the machine directly under hiscontrol, and the frame and yarn, as soon as the yarn has been dyedsufficiently, can be quickly removed and another frame which has beenloaded with yarn can be dropped in its place without loss of time.

In the bottom of the tank is a series of radial steam-pipes, whichreceive steam from an annular connecting-pipe N, and these radial pipeshave orifices therein inclined backward-that is to say, in a directionopposite to the direction of movement of the yarn-can rying frame, sothat the jets of steam issuing from the orifices of the pipes will tendto counteract any tendency which might otherwise exist to cause acurrent of the liquid in 90 the tank in the direction of rotation of theyarn-carrying frame.

It will be evident that friction-gears may replace the rack and piniongears for effecting the rotation of the shafts M.

I am aware that dyeing-machines have here tofore been constructed inwhich a rotating frame has been employed to carrythe yarn around thecircular tank; but in all of such constructions, so far as I am aware,the mech-' I00 anism for rotating the independent yarn-carrying shaftshas been placed at the inner ends of these shafts and a separate inner.tub has been employed for such mechanism, the diameter of the tankbeing necessarily much greater than in the construction employed by me.

Having thus described my invention, I claim and desire to secure byLetters Patent a 1. A machine for dyeing or washing yarn, having incombination a tank A, a vertical bearing-post therein, a driving-shaft,a clutch E, secured thereon, a removable carryingframe F, a clutch-facethereon adapted to engage With the clutch E, radiating yarn-carryingshafts, pinions thereon, bearings on said frame F for the inner andouter ends of said shafts, and a circular rack on the upper edge of thetank, with which said pinions are adapted to engage, substantially asspecified. a

2. The combination of the tank and the rotating yarn-carrying frame withsteam-pipes having openings located so as to discharge jets of steaminto the liquor in the tank in a direction the reverse of the rotatingmovement of the yarn frame, substantially as specified.

3. In a machine for dyeing or washing yarn, the combination of a tank, acircular rack on the upper edge of said tank, a rotatable frame, pinionsh, mounted on stub-shafts, bearings g on the frame for said shafts, andradial yarn-carryin g shafts a, having one end adapted to a squaredorifice in said stub-shafts, the opposite ends of said shafts a beingadapted to open-top bearing-blocks g, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

WILLIAM D. CONNER, HARRY SMITH.
